We always had chickens when I was a kid. I agree about the rooster, one is all you will ever need, or want. From a permaculture perspective chickens are essential, they are great at pest control and cleanup in general. It's amazing how much they will eat, a good portion of the "trash" around your house is actually valuable chicken food, excepting plastics, tin, glass, etc. My mom would even feed them their own eggs shells.... If you plan on doing free range chickens, however, you will need to have a wonderfully comfy place for them to come home to every night and kids to run around and look for egg nests. Our coop/mansion had three sections, one for sleeping (it was just a bunch of elevated 1" dowels, they balance on a bar to sleep, go figure), one for laying (three raised boxes with hay and a few "fake" eggs to make them feel secure, had a trap door in the back for easy access when stealing their days work), and one for general congregation, chicken conferences and community meetings, watering, hiding, etc.... oh yeah, and banty hens are cute, but not worth the effort IMHO.
